Benefits of technology

The system simplifies fluid delivery, improves procedural efficiency, and increases clinical productivity by enabling on-demand fluid delivery and mixing, making endoscopic procedures more effective and reducing the need for disposable components.

Problems solved by technology

By manipulating a set of control knobs, the examiner is able to steer the endoscope during insertion and direct it to a region of interest, in spite of the limitations of such traditional control systems, which may be clumsy, non-intuitive, and friction-limited.
In colonoscopy procedures, typically, 5-10% of patients who arrive for the procedure are inadequately prepared (i.e., the colon is not properly cleared) and are, therefore, turned away.
However, these procedures are made more difficult and time consuming because it requires the physician to flush and evacuate stool or other debris, which represents a loss of productivity.
During an EGD procedure, the mixing of bile and water creates a lot of captivating bubbles.
These bubbles hinder the physician's visibility during the procedure.
This cumbersome and time-consuming process is repeated for any and all types of liquids required in any given endoscopic procedure.

first embodiment

[0030]FIG. 1 illustrates a perspective view of an endoscopic system 100 in accordance with the invention. The endoscopic system 100 includes an imaging endoscope 110 that further includes an endoscope proximal shaft 112 that is electrically, mechanically, and fluidly connected, at one end, to an endoscope proximal connector 114 and, at an opposite end, to a port of a handheld manual controller 116, and an endoscope distal shaft 118 that is electrically, mechanically, and fluidly connected, at one end, to another port of handheld manual controller 116 and that has an endoscope distal tip 120 located at its opposite end for advancing into a patient's body.

[0031]Imaging endoscope 110 is an instrument that allows for the examination of the interior of a tract, lumen or vessel or hollow organ of a patient. Imaging endoscope 110 further includes an illumination mechanism (not shown), an image sensor (not shown), and an elongate shaft that has one or more lumens located therein. Imaging en...

second embodiment

[0060]FIG. 4 illustrates a perspective view of a multi-fluid endoscopic system 400 in accordance with the invention. Multi-fluid endoscopic system 400 includes imaging endoscope 110 that is connected to operator console 122 via endoscope proximal connector 114, as described in reference to FIGS. 1 and 2. Multi-fluid endoscopic system 400 includes pump 128, as described in reference to FIG. 1. Multi-fluid endoscopic system 400 further includes a plurality of fluid sources 410, e.g., a fluid source 410a, 410b, and 410c, that feed tubing 126 via a tubing subassembly 412 that brings together the tubing from the separate fluid sources 410 to a common line, i.e., tubing 126, and wherein each fluid source 410 has an associated pinch valve that allows liquid to reach the pump 128. Each fluid source 410 may take the form of a rigid vessel or a bladder with a capacity of, for example, up to one liter of fluid. Each fluid source 410 may be a refillable vessel, or alternatively, each fluid sour...

third embodiment

[0062]FIG. 5 illustrates a perspective view of a multi-fluid endoscopic system 500 in accordance with the invention. Multi-fluid endoscopic system 500 includes imaging endoscope 110 that is connected to operator console 122 via endoscope proximal connector 114, as described in reference to FIGS. 1 and 2. Multi-fluid endoscopic system 400 also includes multiple fluid sources 410, e.g., fluid source 410a, 410b, and 410c, as described in reference to FIG. 4. However, instead of including tubing sub-assembly 412, each fluid source 410 has its own dedicated length of tubing 126 and dedicated pump 128 that feed endoscope proximal connector 114 of imaging endoscope 110. For example, fluid source 410a is fluidly connected to endoscope proximal connector 114 via a length of tubing 126a that passes through pump 128a, fluid source 410b is fluidly connected to endoscope proximal connector 114 via a length of tubing 126b that passes through pump 128b, and fluid source 410c is fluidly connected t...

Abstract

A fluid delivery system for use with an endoscope. Certain embodiments of the invention include a single, large fluid source and pump installed upon an operator console, in combination with a small fluid reservoir and pump installed within a proximal connector of the imaging endoscope, multiple fluid sources that feed a common fluid channel that are pressurized by a common pump, multiple fluid sources that feed dedicated fluid channels that are pressurized by dedicated pumps, and a small fluid reservoir and pump installed within a handheld manual controller of the imaging endoscope. The fluid delivery endoscopic systems of the present invention provide the user with the flexibility of changing fluids either in advance of a procedure or on-the-fly as needed, instead of relying on fixed fluid sources only.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of U.S. Provisional Application No. 60 / 614,868, filed Sep. 30, 2004.FIELD OF THE INVENTION[0002]The present invention relates to medical devices, in general, and fluid delivery mechanisms for therapeutic and diagnostic endoscopes, in particular.BACKGROUND OF THE INVENTION[0003]As an aid to the early detection of disease, it has become well established that there are major public health benefits that result from regular endoscopic examination of internal structures, such as the alimentary canals and airways, e.g., the esophagus, stomach, lungs, colon, uterus, ureter, kidney, and other organ systems. A conventional imaging endoscope used for such procedures is formed of a flexible tube that has a fiber optic light guide that directs illuminating light from an external light source to the distal tip, where it exits the endoscope and illuminates the tissue to be examined. Frequently, additional optica...
